How can negative pressure be avoided during the condensation of steam in a heat exchanger? If steam is not continuously replenished, will a negative pressure be created in the heat exchanger after the steam in the condenser is condensed? ?
It’s a graphite condenser; how can this be avoided? ?
No steam accumulation creates negative pressure; to avoid this, it is necessary to release air.
It is necessary to install a non-condensable gas vent line
Are there any methods for automatic control? How to set it up to prevent a vacuum from forming? Should the non-condensate pipeline valve remain open all the time? ?
Do you have any tips for self-control, sir? How to set it up to prevent a vacuum from forming? Should the non-condensate pipeline valve remain open all the time? ?
Continuous steam inflow and continuous condensate outflow will not result in negative pressure； Just drain the water before shutting down.
